[PATCH 0/5] perf tools: Pipe fixes

From: Jiri Olsa
Date: Thu May 07 2020 - 05:50:36 EST


hi,
sending changes that allows callchain detection in pipe mode,
fixing followign use case:

# perf record --no-buffering --call-graph dwarf -e sdt_rtld:init_start -a -o - | perf --no-pager script -i -

plus change that allows to read pipe data from file:

# perf record -o - sleep 1 > /tmp/perf.pipe.data
# perf report -i /tmp/perf.pipe.data

plus unrelated build fix.

Also reachable in here:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/pipe

thanks,
jirka
